Diagnostic aids for CICS

We can use the CKQC transaction (the CICS adapter control panels) to display information about queue manager tasks, and what state they are in (for example, a GET WAIT). See the WebSphere MQ for z/OS System Administration Guide for information about CKQC.

The application development environment is the same as for any other CICS application, and so we can use any tools normally used in that environment to develop WebSphere MQ applications. In particular, the CICS execution diagnostic facility (CEDF) traps entry to and exit from the CICS adapter for each MQI call, as well as trapping calls to all CICS API services. Examples of the output produced by this facility are given in Appendix D. Examples of CEDF output.

The CICS adapter also writes trace entries to the CICS trace. These entries are described in Appendix C. CICS adapter trace entries.

Additional trace and dump data is available from the CICS region. These entries are as described in the CICS Problem Determination Guide.
